Cut-resistant fabric, articles

ABSTRACT

Provided among other things is a cut-resistant article comprising: a cut-resistant synthetic fabric; and adherent to the fabric a layer of polyurethane polymer in which is dispersed mineral fibers of hardness about 4 Mohs or higher and having L/D ratio between about 8 and about 16, wherein the article has a cut resistance by ISO 13997:1999 of 2 or higher.

The present application relates generally to cut-resistant polymer-coated fabrics that incorporate mineral fibers in the polymer coating.

The current application is a continuation-in-part of U.S. Ser. No. 14/933,122, filed Nov. 5, 2015, and claims benefit of U.S. Ser. No. 62/131,315, filed Mar. 11, 2015, U.S. Ser. No. 62/083,636, filed Nov. 24, 2014, and U.S. Ser. No. 62/075,597, filed Nov. 5, 2014, the contents of each of which are incorporated herein in their entireties.

Henssen et al., U.S. Pat. Publ. 2013/0125283, describes articles having mineral fibers in a polymer coating where the fibers are said to have a range of L/D ratios. The Hessen application however only experimentally illustrates these articles with mineral fibers having an L/D ratio of 25.6. Nothing in Henssen discloses or suggests that using an L/D ratio of 5 to 16 (by the L/D measurement method set forth in Example 1 of Henssen) would have remarkably greater cut resistance than using a similar mineral fiber with L/D ratio of 17.9.

Neither does Henssen disclose or suggest that polyurethane/nitrile coated cut resistant polyamide fabric would have the cut resistance described herein.

DETAILED DESCRIPTION

FIG. 1 depicts schematically a fabric 10 coated with a polymer layer 20 in which are dispersed fibers 22.

The cut-resistant articles of the invention are formed on fabric supports, such as fabric glove liners. The fabric can be, for example, knitted, woven or non-woven, and/or seamless or cut and sewn. The fabric can comprise for example about 70, 80 or 85% or more cut-resistant yarns (by wt). Cut resistant yarns comprise, for example, ultra high molecular weight polyethylene (UHMWPE), such as DYNEEMA®, TSUNOOGA®, a meta-aramid, such as NOMEX®, or a para-aramid, such as KEVLAR® or TWARON® (meta and para-aramids being cut-resistant polyamides). Elastic yarns, such as LYCRA®, SPANDEX®, or ELASTANE® may be used to impart flexibility. In embodiments, the fabric includes (e.g., about 70, 80 or 85% or more by wt) polycarbonate or glass fibers (including without limitation glass fiber yarn fabric). In embodiments, the fabric comprises about 70, 80 or 85% or more of a polyamide cut-resistant yarn. In embodiments, the fabric is about 98% or more, or about 100% cut-resistant yarn, such as cut-resistant polyamide yarn.

In other embodiments, the fabric is cotton, polycotton, polyester, polypropylene, or the like, or mixtures thereof.

To produce the article, typically the fabric is fitted on a former, namely a solid support shaped to support the contours of the final shape of the article. The fitting can be such that the fabric is stretched somewhat over the final sizing. Typically, the article is dipped into or has applied to it a coagulant composition, such as one containing calcium nitrate, calcium sulfate, acetic acid or another coagulant. Typically, the coagulant composition on the fabric is dried to remove solvent.

Then, the fabric on the former is dipped into, or otherwise has applied to it, an elastomer composition formulated to coagulate on contact with the coagulant. Additional coatings may be applied, with or without intervening coagulant applications. In one embodiment, the first elastomer coating includes dispersed therein the fibers discussed herein. In embodiments, the fiber-containing elastomer is the only elastomer (latex) layer applied.

In embodiments, the elastomer layer is leached, typically in aqueous fluid, prior to heat curing. After heat curing, the elastomer surface can be, in embodiments, chlorinated, followed in embodiments by contacting with a neutralization formulation.

An illustrative manufacturing process is shown in FIG. 2. In step 202, the fabric is loaded onto a former. In step 204, coagulant is applied to the fabric. This step, as with all steps marked with an asterisk (*) is optional. In step 206, the coagulant is dried. In step 208, elastomer is applied to the fabric. In step 210, excess elastomer is allowed to drip off. In step 212, the elastomer is air dried. In a further option, the former is re-oriented so that the article with its coating primarily faces up. Step 214 indicates that steps 204 to 212 or 208 to 212 can be repeated once or more. In step 216, texture is applied to the elastomer surface. In step 218, the article is leached or rinsed. In step 220, the article is cured, typically with heat, to crosslink the elastomer.

In embodiments, such as those using a substantially polyamide cut-resistant fabric, the mineral fibers used in the invention have a L/D ratio of between about 8 (8:1) and about 27 (27:1). In embodiments, the mineral fibers used in the invention have a L/D ratio of between about 9 and about 21. In embodiments, the mineral fibers used in the invention have a L/D ratio of between about 8 or 9 and about 16. The L/D ratio is taken based on the mass weighted average value for length, L, and on the mass weighted average value for diameter, D. (Applicant understands that Lapinus Fibres (Netherlands) measures L as the mass weighted average. If that understanding is incorrect, then L is as measured by Lapinus Fibres for fibers of the type described herein.)

In embodiments, the diameter D for the fibers (mass weighted ay.) is from about 5 to about 23 micron, or from about 5 to about 12 or 15 micron. In embodiments, the length, L, for the fibers (mass weighted ay.) is from about 100 to about 210 micron (100×10⁻⁶ m to 210×10⁻⁶ m), or from about 100 to about 170 micron.

In embodiments, the mineral fibers used in the invention have a hardness of about 4 Mohs or higher. In embodiments, the mineral fibers have a hardness of about 5 Mohs or higher, or about 6 Mohs. The fibers can be, for example, uniformly distributed in the polymer layer.

In embodiments, the fiber content in the elastomer suspension (prior to coagulation and curing) is about 4% to about 18% w/w, such as about 8 to about 16%, or about 8.5% to about 15.5%, or about 10% to about 14%. In embodiments, the fiber content in the elastomer suspension (prior to coagulation and curing) is about 4% to about 10% w/w, such as about 5 to about 7%. In embodiments, the fiber content in the elastomer suspension (prior to coagulation and curing) is about 7% to about 13% w/w, such as about 8 to about 12%.

Illustrative fibers include, from Lapinus Fibres (Netherlands), Rockbrake RB215 (L=150, D=9, L/D=17), Rockforce MS603 (L=125, D=9, L/D=14), and Coatforce CF10 (L=125, D=7, L/D=18), and from NYCO Minerals NYAD MG (L=207, D=23, L/D=9).

In embodiments, the thickness of the polymer coating with mineral fiber is from about 0.07 to about 0.15 mm, or from about 0.5 mm to about 1.4 mm, such as about 0.7 mm to about 1.1 mm. The layer thickness can be measured by microscopic examination of a representative cross-section. The inner surface of the elastomer layer can be expected to include a number of penetrations into the fabric. These penetrations can be ignored, with the thickness being an average of a representative number of locations away from such penetrations.

In embodiments, the thickness of the fabric is from about 0.7 to about 4 mm, or about 0.91 to about 1.05 mm.

The elastomeric layers may be natural rubber latex (including Guayule latex), synthetic rubber latex, or the like, and combinations thereof. The synthetic rubber latex may be selected, for example, from the group comprised of polychloroprene, acrylonitrile butadiene copolymer (NBR or “nitrile”) (such as carboxylated acrylonitrile butadiene copolymer), polyisoprene, polyurethane, styrene-butadiene, butyl, and combinations thereof. Other polymer coating techniques, such as water or solvent-based resin coatings can be used. For example, a polyurethane (such as one having hydrophilic groups) can be applied as a suspension in N-methyl pyrrolidone (NMP), dimethylacetamide (DMAC), or dimethyl sulfoxide (DMSO), with the addition of fiber.

In embodiments, the elastomeric layer with dispersed mineral fiber is about 5% or more polyurethane and about 60% or more nitrile (wt).

The article of the invention has a cut-resistance, measured with a cutting implement addressed to the polymer with dispersed mineral fiber coated side of the article, with the measurement pursuant to International ISO 13997:1999. In embodiments, the cut-resistance is 2.1600 grams or higher. In embodiments, the article has a cut-resistance of 4 or higher. An embodiment with a particularly high cut-resistance of say 9.1600 grams (20 mm) can be directly measured by the standard of International ISO 13997:1999, by adjusting loads as needed and retesting to collect five data points in the 5 to 20 mm cut-through length range. This value was compared with a control reference, without mineral fibers. In embodiments, the cut-resistance of this sample was 300 grams (20 mm). Furthermore, the distance until cut can be normalized to a load of 1000 grams, by fitting the appropriate normalization function to the results at various higher loads, the embodiment with cut-resistance of 9.1600 grams by ISO 13997:1999 is expected to have a cut-resistance of about 191.09 mm (1000 grams).

Articles according to the invention can include glove, clothing for endeavors with a high risk of cutting (such as motorcycle riding), jackets, sweaters, pants, gators, chaps, wrist covers, forearm covers, arm covers, facemasks, balaclavas, and the like. It will be recognized that in some embodiments selected high risk surfaces on the article will be coated with the polymer with dispersed mineral fiber.

All ranges recited herein include ranges therebetween, and can be inclusive or exclusive of the endpoints. Optional included ranges are from integer values therebetween (or inclusive of one original endpoint), at the order of magnitude recited or the next smaller order of magnitude. For example, if the lower range value is 0.2, optional included endpoints can be 0.3, 0.4, . . . 1.1, 1.2, and the like, as well as 1, 2, 3 and the like; if the higher range is 8, optional included endpoints can be 7, 6, and the like, as well as 7.9, 7.8, and the like. One-sided boundaries, such as 3 or more, similarly include consistent boundaries (or ranges) starting at integer values at the recited order of magnitude or one lower. For example, 3 or more includes 4 or more, or 3.1 or more.

In embodiments, the article has one or more features indicative of layer of polymer being applied by a process wherein coagulant is applied to the cut-resistant synthetic fabric to coagulate a coagulation-sensitive dispersion of polymer to form the layer of polymer. Such an indicator can include for example the presence of a detectable coagulating salt used for coagulation in an amount greater than would be expected but for the recited coagulation method. Such an indicator can include for example the lack of “break-through” in an amount that would be expected given the fabric (e.g., material, weave density, or the like) in the absence of applying coagulant to the fabric (which tends to create dams at the fabric interstices, limiting break-through). Break-through is where polymer is formed on the interior of a fabric liner.

Specific embodiments according to the methods of the present invention will now be described in the following examples. The examples are illustrative only, and are not intended to limit the remainder of the disclosure in any way.

EXAMPLE 1

Gloves made with 85% polyamide yarn were coated with a blend of polyurethane/nitrile formulation, by dipping the glove into a coagulant. The coagulant is dried and the glove was then dipped into the elastomer formulation. The gloves were vulcanized for around 40 minutes, and 120° C. These gloves were used as control reference (0% fibers). The same process was studied for formulations containing different percentages of mineral fibers (as showed in FIG. 3).

The results are shown in FIG. 3, in which 12% and 18% Rockforce MS603 achieved a Level 4 cut-resistance (according with ISO 13997:1999), with the 18% sample measured at 9.15.7 N (or 1600 grams/20 mm). 18% CoatForce—CF10 also achieved a Level 4 cut-resistance (14.4 N according with ISO 13997:1999). In FIG. 3, the cut-resistances achieved with Rockforce MS603 are shown with filed diamonds (♦); and those achieved with CoatForce CF10 are shown with filled squares (▪). A cut level ≥4 is indicated in the Figure by a horizontal line.

EXAMPLE 2

Gloves made with cotton (cut and sewn) were coated with a blend of polyurethane/nitrile formulation, by dipping the glove into a coagulant. The coagulant is dried and the glove was then dipped into the elastomer formulation. The gloves were vulcanized for around 40 minutes, and 120° C. These gloves were used as control reference (0% fibers). The same process was studied for formulations containing different percentages of mineral fibers (as showed in FIG. 4A).

The results are shown in FIG. 4A, in which 6% Rockforce MS603 achieved a Level 3 cut-resistance (according with EN388). By ANSI/ISEA, and 6% achieved Level 3 cut-resistance (<1000 grams) (FIG. 4B.)
